ST31500341AS vs 0F12117

So, thinking about how the sync of the ST1500341AS to 0F12117 was slightly slower than the sync of 0F12117 to 0F12117, I wondered what specs about the new drive would edge out.

Specs for the ST31500341AS that I could track down include:

Formatted capacity               1500GB
Guaranteed sectors               2930277168

Specs for the 0F12117 that I could track down include:

Total Logical Data Bytes         2000398934016 bytes
Number of sectors                3907029168
Track-to-track seek time         0.5ms typ 0.7ms max read
                                 0.6ms typ 0.8ms max write

Average seek, write              <10.0ms
Average Latency                  5.05 ms

Probably all comes down to recording density....the Hitachi 2TB having more data stored on in less area than the Seagate 1.5TB, makes the Hitachi faster than the Seagate....

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
